Shape memory alloys (SMA) represent an important class of smart metallic materials employed in various innovative applications thanks to their unique thermomechanical behavior. Since the 1980s, several SMA constitutive models have been proposed and implemented into both commercial and academic finite element analysis…
Most of titanium alloys contain two phases at temperatures of processing and exploitation: -phase with HCP lattice and -phase with BCC lattice. Stability of two-phase structure and thermodynamics of / transformation, which occurs in a wide range of temperatures, considerably depend on the specific energy of interp…
Nanoscale transport phenomena in a membrane electrode assembly (MEA) of polymer electrolyte fuel cell (PEFC) is analyzed by large scale molecular dynamics (MD) simulations. Especially, the transport phenomena of proton in polymer electrolyte membrane (PEM) which has highly anisotropic water structures, oxygen permeabi…
TBC (Thermal Barrier Coating) protects structural components from high temperature environment of gas turbines. The TBC consists of ceramic top coat and metallic bond coat, deteriorate by the high temperature operating condition. CMAS (CaO-MgO-Al2O3-SiO2) infiltration into the top coat is also one of degradation mode…
This study evaluates the cell behavior of HeLa cells in vitro on fibroin and polypropylene. In order to determine cell proliferation in culture much fibroin material such as polypropylene, as the number of cells / sample was performed by the metabolic reduction of 3-(4,5- dimetiltiazol-2-ilo)-2,5-difeniltetrazol Bromi…
This paper discloses viable eco-solutions concerning the formulation and the performance of biocomposites and bioblends formulated based on polypropylene (PP), polyamide (PA6), and acrylonitrile-butadiene-styrene (ABS) and designated for the fabrication of interior automotive parts. Biocomposites containing up to 40 w…
Quantum dot solar cells require very high absorption of the second low-energy photon to operate in the intermediate band regime. We study guided-mode resonance backside gratings demonstrating strong enhancement of intraband optical transitions.
The concentration of zinc on the surface of brass plating is higher than that of the average composition of the brass. Better retention of adhesion after humidity aging is achieved at a higher zinc content of brass, having the positive effect of ZnO at brass surface. ZnO at the surface inhibits the formation of excess…
CERN's Super Proton Synchrotron (SPS) high-energy internal dump (Target Internal Dump Vertical Graphite, known as TIDVG) is required to intercept beams from 10² to 450 GeV. The equipment installed in 2014 (TIDVG#3) featured an absorbing core composed of different materials surrounded by a water-cooled copper jacket, w…
Fluid inclusion studies on pegmatitic bodies are performed to gain insight on the conditions during the formation of the pegmatites as FIs can be seen to directly mirror the fluids that were present during the formation of, most commonly, the quartz in the pegmatite. Continued progress in the methodology of measuremen…
Microorganisms give an early and integrated measure of soil functioning. In particular, soil microbial respiration is recommended for monitoring soil quality. The present study aims to determine the capacity of Albit® (poly-β-hydroxybutyrate, PHB) to reduce the detrimental effects of pesticides on soil microbial respi…
Background: Cytoreductive surgery combined to hyperthermic intraperitoneal chemotherapy (HIPEC) is the standard of care for selected patients with peritoneal surface malignancies. Preclinical studies, especially when performed on animal models, provide a framework for improvement of this treatment. This study aims to…
In order to experimentally verify the fracture mechanism of a precipitation-hardened superalloy with internal hydrogen, we performed SEM observation of fracture surface and cross sectional area beneath the fracture surface of an A286 iron-based superalloy subjected to an internal hydrogen tensile testing, which was ca…
Pt/BEA–Al 2 O 3 catalysts were prepared from two type precursors (H 2 PtCl 6 and [Pt(NH 3 ) 4 ]Cl 2 ); the platinum content was varied between 0.02 and 0.5 wt %. The catalyst testing for hydroisomerization of a benzene-heptane mixture at 1.5 MPa and 230–330 °C demonstrated high selectivities to methylcyclopentane of t…
In this paper, we combine experimental measurements and numerical techniques to investigate the electromagnetic scattering of a solution of hybrid polyethylene glycol-gold (PEG-Au NPs) nanoparticles before and after bio-conjugation with an enzyme, the Arsenate reductase, in brief ArsC. In particular, we unveil the ori…
An amorphous metal alloy of the FeCrB system was studied during the crystallization by thermal annealing. Such an alloy is a perspective candidate for the role of an intermediate layer in multilayer covering for cutting tools. By the using of the thermoelectric voltage measurement, positron annihilation spectroscopy,…
O Centro de Desenvolvimento da Tecnologia Nuclear (CDTN) é um instituto de pesquisa administrado pela Comissão Nacional de Energia Nuclear (CNEN), órgão do Ministério da Ciência, Tecnologia, Inovação e Comunicações (MCTIC) do Brasil.. O CDTN tem em suas instalações um reator nuclear do tipo Triga modelo Mark I. A água…
The carbon nanowall (CNW) layers were grown from a gas mixture of hydrogen and methane, activated by a DC glow discharge, on Si substrates (Si/CNW layered structure). The second layer of CNW was grown either on the first layer (Si/CNW/CNW structure) or on Ni or NiO films deposited on the first CNW layer (Si/CNW/Ni/CNW…
The fresh water bodies of Sawaimadhopur district, Rajasthan were surveyed for enlisting of different phytotoplankton diversity. The Chlrococcales are phototrophic micro-algal group with great diversity and cosmopolitan in their distribution. Forty two species were recorded and described in present paper from study are…
Germanium is living a renaissance in the field of silicon photonics, where it is used as absorption element in waveguide photodetectors. Since a moderate reverse bias is enough to deplete the Ge absorber, pushing the carriers in the velocity saturation regime, we discuss here the main challenges involved in the three-…
